Suppose that a silicon semiconductor is doped
Chapter 40, Problem 40.47(choose chapter or problem)
Suppose that a silicon semiconductor is doped withphosphorus so that one silicon atom in 1.2 X 106 isreplaced by a phosphorus atom. Assuming that the extraelectron in every phosphorus atom is donated to theconduction band, by what factor is the density of conductionelectrons increased? The density of silicon is 2330 kg/m3,and the density of conduction electrons in pure silicon isabout 1016 m-3 at room temperature.
